I do believe there is a big difference between cows and goats milk and I have the same feeling about giving it to your baby and giving it to yourself. Goat milk has less lactose than cows milk so that if your baby is reacting, this maybe the reason. Goat milk proteins have many significant differences in their amino acid compositions from the milk of cows, (Jenness, 1980; Boulanger et al., 1984; Addeo et al., 1988; Ambrosoli et al., 1988). The major difference is that it is that the fat cells are smaller in goat milk and therefore easier to digest.
